git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq updates from Thomas Gleixner: "The irq departement proudly presents: - A rework of the core infrastructure to optimally spread interrupt for multiqueue devices. The first version was a bit naive and failed to take thread siblings and other details into account. Developed in cooperation with Christoph and Keith. - Proper delegation of softirqs to ksoftirqd, so if ksoftirqd is active then no further softirq processsing on interrupt return happens. Otherwise we try to delegate and still run another batch of network packets in the irq return path, which then tries to delegate to ksoftirqd ..... - A proper machine parseable sysfs based alternative for /proc/interrupts. - ACPI support for the GICV3-ITS and ARM interrupt remapping - Two new irq chips from the ARM SoC zoo: STM32-EXTI and MVEBU-PIC - A new irq chip for the JCore (SuperH) - The usual pile of small fixlets in core and irqchip drivers" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (42 commits) softirq: Let ksoftirqd do its job genirq: Make function __irq_do_set_handler() static ARM/dts: Add EXTI controller node to stm32f429 ARM/STM32: Select external interrupts controller drivers/irqchip: Add STM32 external interrupts support Documentation/dt-bindings: Document STM32 EXTI controller bindings irqchip/mips-gic: Use for_each_set_bit to iterate over local IRQs pci/msi: Retrieve affinity for a vector genirq/affinity: Remove old irq spread infrastructure genirq/msi: Switch to new irq spreading infrastructure genirq/affinity: Provide smarter irq spreading infrastructure genirq/msi: Add cpumask allocation to alloc_msi_entry genirq: Expose interrupt information through sysfs irqchip/gicv3-its: Use MADT ITS subtable to do PCI/MSI domain initialization irqchip/gicv3-its: Factor out PCI-MSI part that might be reused for ACPI irqchip/gicv3-its: Probe ITS in the ACPI way irqchip/gicv3-its: Refactor ITS DT init code to prepare for ACPI irqchip/gicv3-its: Cleanup for ITS domain initialization PCI/MSI: Setup MSI domain on a per-device basis using IORT ACPI table ACPI: Add new IORT functions to support MSI domain handling ...

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI updates from Rafael Wysocki: "First off, the ACPICA code in the kernel is updated to upstream revision 20160831 that brings in a few bug fixes and cleanups. In particular, it is possible to mask GPEs now (and the sysfs interface for GPE control is fixed on top of that), problems related to the table loading mechanism are fixed and all code related to FADT version 2 (which has never been part of the ACPI specification) is dropped. On the new features front, there is a new watchdog driver based on the ACPI WDAT (ACPI Watchdog Action Table), needed on some platforms to replace the iTCO watchdog that doesn't work there, and some UART devices get new definitions of built-in properties (to be accessed via the generic device properties API). Also, included is a fix for an ACPI-related PCI resorces allocation issue and a few problems in the EC driver and in the button and battery drivers are fixed. In addition to that, the ACPI CPPC library is updated to make batching of requests sent over the PCC channel possible (which reduces the PCC usage overhead substantially in some cases) and to support functional fixed hardware (FFH) type of CPPC registers access (which will allow CPPC to be used on x86 too in the future). As usual, there are some assorted fixes and cleanups too. Specifics: - Update of the ACPICA code in the kernel to upstream revision 20160831 with the following major changes: * New mechanism for GPE masking. * Fixes for issues related to the LoadTable operator and table loading. * Fixes for issues related to so-called module-level code (MLC), that is AML that doesn't belong to any methods. * Change of the return value of the _OSI method to reflect the Windows behavior. * GAS (Generic Address Structure) support fix related to 32-bit FADT addresses. * Elimination of unnecessary FADT version 2 support. * ACPI tools fixes and cleanups. From Bob Moore, Lv Zheng, and Jung-uk Kim. - ACPI sysfs interface updates to fix GPE handling (on top of the new GPE masking mechanism in ACPICA) and issues related to table loading (Lv Zheng). - New watchdog driver based on the ACPI WDAT (ACPI Watchdog Action Table), needed on some platforms to replace the iTCO watchdog that doesn't work there and related updates of the intel_pmc_ipc, i2c/i801 and MFD/lcp_ich drivers (Mika Westerberg). - Driver core fix to prevent it from leaking secondary fwnode objects during device removal (Lukas Wunner). - New definitions of built-in properties for UART in ACPI-based x86 SoC drivers and a 8250_dw driver quirk for the APM X-Gene SoC (Heikki Krogerus). - New device ID for the Vulcan SPI controller and constification of local strucures in the AMD SoC (APD) ACPI driver (Kamlakant Patel, Julia Lawall). - Fix for a bug causing the allocation of PCI resorces to fail if ACPI-enumerated child platform devices are registered below the PCI devices in question (Mika Westerberg). - Change of the default polarity for PCI legacy IRQs to high on systems booting wth ACPI on platforms with a GIC interrupt controller model fixing the discrepancy between the specification and HW behavior (Lorenzo Pieralisi). - Fixes for the handling of system suspend/resume in the ACPI EC driver and update of that driver to make it cope with the cases when the EC device defined in the ECDT has to be used throughout the entire system life cycle (Lv Zheng). - Update of the ACPI CPPC library to allow it to batch requests sent over the PCC channel (to reduce overhead), to support the fixed functional hardware (FFH) CPPC registers access type, to notify the mailbox framework about TX completions when the interrupt flag is set for the PCC mailbox, and to support HW-Reduced Communication Subspace type 2 (Ashwin Chaugule, Prashanth Prakash, Srinivas Pandruvada, Hoan Tran). - ACPI button driver fix and documentation update related to the handling of laptop lids (Lv Zheng). - ACPI battery driver initialization fix (Carlos Garnacho). - ACPI GPIO enumeration documentation update (Mika Westerberg). - Assorted updates of the core ACPI bus type code (Lukas Wunner, Lv Zheng). - Assorted cleanups of the ACPI table parsing code and the x86-specific ACPI code (Al Stone). - Fixes for assorted ACPI-related issues found in linux-next (Wei Yongjun)" * tag 'acpi-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (98 commits) ACPI / documentation: Use recommended name in GPIO property names watchdog: wdat_wdt: Fix warning for using 0 as NULL watchdog: wdat_wdt: fix return value check in wdat_wdt_probe() platform/x86: intel_pmc_ipc: Do not create iTCO watchdog when WDAT table exists i2c: i801: Do not create iTCO watchdog when WDAT table exists mfd: lpc_ich: Do not create iTCO watchdog when WDAT table exists ACPI / bus: Adjust ACPI subsystem initialization for new table loading mode ACPICA: Parser: Fix a regression in LoadTable support ACPICA: Tables: Fix "UNLOAD" code path lock issues ACPI / watchdog: Add support for WDAT hardware watchdog ACPI / platform: Pay attention to parent device's resources PCI: Add pci_find_resource() ACPI / CPPC: Support PCC with interrupt flag ACPI / sysfs: Update sysfs signature handling code ACPI / sysfs: Fix an issue for LoadTable opcode ACPICA: Tables: Fix a regression in acpi_tb_find_table() ACPI / tables: Remove duplicated include from tables.c ACPI / APD: constify local structures x86: ACPI: make variable names clearer in acpi_parse_madt_lapic_entries() x86: ACPI: remove extraneous white space after semicolon ...

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "Traditionally, cpufreq is the area with the greatest number of changes, but there are fewer of them than last time. There also is some activity in the generic power domains and the devfreq frameworks, a couple of system suspend and hibernation fixes and some assorted changes in other places. One new feature is the cpufreq change to allow the scheduler to pass hints to the governors' utilization update callbacks and some code rework based on that. Another one is the support for domain removal in the generic power domains framework. Also it is now possible to use hibernation with PAGE_POISONING_ZERO enabled and devfreq supports the RockChip DFI controller and the rk3399 DMC. The rest of the changes is mostly fixes and cleanups in a number of places. Specifics: - Add a mechanism for passing hints from the scheduler to cpufreq governors via their utilization update callbacks and use it to introduce "IOwait boosting" into the schedutil governor and intel_pstate that will make them boost performance if the enqueued task was previously waiting on I/O (Rafael Wysocki). - Fix a schedutil governor problem that causes it to overestimate utilization if SMT is in use (Steve Muckle). - Update defconfigs trying to use the schedutil governor as a module which is not possible any more (Javier Martinez Canillas). - Update the intel_pstate's pstate_sample tracepoint to take "IOwait boosting" into account (Srinivas Pandruvada). - Fix a problem in the cpufreq core causing it to mishandle the initialization of CPUs registered after the cpufreq driver (Viresh Kumar, Rafael Wysocki). - Make the cpufreq-dt driver support per-policy governor tunables, clean it up and update its Kconfig description (Viresh Kumar). - Add support for more ARM platforms to the cpufreq-dt driver (Chanwoo Choi, Dave Gerlach, Geert Uytterhoeven). - Make the cpufreq CPPC driver report frequencies in KHz to avoid user space compatiblility issues (Al Stone, Hoan Tran). - Clean up a few cpufreq drivers (st, kirkwood, SCPI) a bit (Colin Ian King, Markus Elfring). - Constify some local structures in the intel_pstate driver (Julia Lawall). - Add a Documentation/cpu-freq/ entry to MAINTAINERS (Jean Delvare). - Add support for PM domain removal to the generic power domains (genpd) framework, add new DT helper functions to it and make it always enable debugfs support if available (Jon Hunter, Tomeu Vizoso). - Clean up the generic power domains (genpd) framework and make it avoid measuring power-on and power-off latencies during system-wide PM transitions (Ulf Hansson). - Add support for the RockChip DFI controller and the rk3399 DMC to the devfreq framework (Lin Huang, Axel Lin, Arnd Bergmann). - Add COMPILE_TEST to the devfreq framework (Krzysztof Kozlowski, Stephen Rothwell). - Fix a minor issue in the exynos-ppmu devfreq driver and fix up devfreq Kconfig indentation style (Wei Yongjun, Jisheng Zhang). - Fix the system suspend interface to make suspend-to-idle work if platform suspend operations have not been registered (Sudeep Holla). - Make it possible to use hibernation with PAGE_POISONING_ZERO enabled (Anisse Astier). - Increas the default timeout of the system suspend/resume watchdog and make it depend on EXPERT (Chen Yu). - Make the operating performance points (OPP) framework avoid using OPPs that aren't supported by the platform and fix a build warning in it (Dave Gerlach, Arnd Bergmann). - Fix the ARM cpuidle driver's return value (Christophe Jaillet). - Make the SmartReflex AVS (Adaptive Voltage Scaling) driver use more common logging style (Joe Perches)" * tag 'pm-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (58 commits) PM / OPP: Don't support OPP if it provides supported-hw but platform does not cpufreq: st: add missing \n to end of dev_err message cpufreq: kirkwood: add missing \n to end of dev_err messages PM / Domains: Rename pm_genpd_sync_poweron|poweroff() PM / Domains: Don't measure latency of ->power_on|off() during system PM PM / Domains: Remove redundant system PM callbacks PM / Domains: Simplify detaching a device from its genpd PM / devfreq: rk3399_dmc: Remove explictly regulator_put call in .remove PM / devfreq: rockchip: add PM_DEVFREQ_EVENT dependency PM / OPP: avoid maybe-uninitialized warning PM / Domains: Allow holes in genpd_data.domains array cpufreq: CPPC: Avoid overflow when calculating desired_perf cpufreq: ti: Use generic platdev driver cpufreq: intel_pstate: Add io_boost trace partial revert of "PM / devfreq: Add COMPILE_TEST for build coverage" cpufreq: intel_pstate: Use IOWAIT flag in Atom algorithm cpufreq: schedutil: Add iowait boosting cpufreq / sched: SCHED_CPUFREQ_IOWAIT flag to indicate iowait condition PM / Domains: Add support for removing nested PM domains by provider PM / Domains: Add support for removing PM domains ...

Summary: - Support for execute-only page permissions - Support for hibernate and DEBUG_PAGEALLOC - Support for heterogeneous systems with mismatches cache line sizes - Errata workarounds (A53 843419 update and QorIQ A-008585 timer bug) - arm64 PMU perf updates, including cpumasks for heterogeneous systems - Set UTS_MACHINE for building rpm packages - Yet another head.S tidy-up - Some cleanups and refactoring, particularly in the NUMA code - Lots of random, non-critical fixes across the board" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (100 commits) arm64: tlbflush.h: add __tlbi() macro arm64: Kconfig: remove SMP dependence for NUMA arm64: Kconfig: select OF/ACPI_NUMA under NUMA config arm64: fix dump_backtrace/unwind_frame with NULL tsk arm/arm64: arch_timer: Use archdata to indicate vdso suitability arm64: arch_timer: Work around QorIQ Erratum A-008585 arm64: arch_timer: Add device tree binding for A-008585 erratum arm64: Correctly bounds check virt_addr_valid arm64: migrate exception table users off module.h and onto extable.h arm64: pmu: Hoist pmu platform device name arm64: pmu: Probe default hw/cache counters arm64: pmu: add fallback probe table MAINTAINERS: Update ARM PMU PROFILING AND DEBUGGING entry arm64: Improve kprobes test for atomic sequence arm64/kvm: use alternative auto-nop arm64: use alternative auto-nop arm64: alternative: add auto-nop infrastructure arm64: lse: convert lse alternatives NOP padding to use __nops arm64: barriers: introduce nops and __nops macros for NOP sequences arm64: sysreg: replace open-coded mrs_s/msr_s with {read,write}_sysreg_s ...

2016-09-23arm64: arch_timer: Work around QorIQ Erratum A-008585Scott Wood2-0/+11
Erratum A-008585 says that the ARM generic timer counter "has the potential to contain an erroneous value for a small number of core clock cycles every time the timer value changes". Accesses to TVAL (both read and write) are also affected due to the implicit counter read. Accesses to CVAL are not affected. The workaround is to reread TVAL and count registers until successive reads return the same value. Writes to TVAL are replaced with an equivalent write to CVAL. The workaround is to reread TVAL and count registers until successive reads return the same value, and when writing TVAL to retry until counter reads before and after the write return the same value. The workaround is enabled if the fsl,erratum-a008585 property is found in the timer node in the device tree. This can be overridden with the clocksource.arm_arch_timer.fsl-a008585 boot parameter, which allows KVM users to enable the workaround until a mechanism is implemented to automatically communicate this information. This erratum can be found on LS1043A and LS2080A.

2016-09-14genirq: Expose interrupt information through sysfsCraig Gallek1-0/+53
Information about interrupts is exposed via /proc/interrupts, but the format of that file has changed over kernel versions and differs across architectures. It also has varying column numbers depending on hardware. That all makes it hard for tools to parse. To solve this, expose the information through sysfs so each irq attribute is in a separate file in a consistent, machine parsable way. This feature is only available when both CONFIG_SPARSE_IRQ and CONFIG_SYSFS are enabled. Examples: /sys/kernel/irq/18/actions: i801_smbus,ehci_hcd:usb1,uhci_hcd:usb7 /sys/kernel/irq/18/chip_name: IR-IO-APIC /sys/kernel/irq/18/hwirq: 18 /sys/kernel/irq/18/name: fasteoi /sys/kernel/irq/18/per_cpu_count: 0,0 /sys/kernel/irq/18/type: level /sys/kernel/irq/25/actions: ahci0 /sys/kernel/irq/25/chip_name: IR-PCI-MSI /sys/kernel/irq/25/hwirq: 512000 /sys/kernel/irq/25/name: edge /sys/kernel/irq/25/per_cpu_count: 29036,0 /sys/kernel/irq/25/type: edge [ tglx: Moved kobject_del() under sparse_irq_lock, massaged code comments and changelog ] Signed-off-by: Craig Gallek <kraig@google.com> Cc: David Decotigny <decot@google.com> Link: http://lkml.kernel.org/r/1473783291-122873-1-git-send-email-kraigatgoog@gmail.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

The driver has supported touchscreen-fw-name to specify the firmware to load since it has been merged, but this was omitted from the dt-binding documentation. During review of adding touchscreen-fw-name to the binding documentation it was brought up that there is a standard property name called "firmware-name" for this, which should be used. Since there are no users of touchscreen-fw-name yet, this commit adds documentation of "firmware-name" to the dt-binding documentation and switches the driver over to use this. This commit also makes the driver add a "silead/" prefix to the firmware name from dt before calling request_firmware. That the firmware files are stored under /lib/firmware/silead under Linux is an implementation detail and does not belong in devicetree.
